I've been using the 'dremel' to cut slots on the lower side of the hood for years...works great.

With due respect I don’t think turning the ring of the circular polarizer is the gist of the post. It seems to be where to stop turning the ring.

Would that be determined by looking through the viewfinder?
At least that is what I do.
If that method is incorrect I would like to learn the correct method.
Thx in advance.

Hi gang,
When casually shooting with my 17 - 40mm 4.0L Canon lens outfitted with a B+W circular polarizer, I find it awkward to have to keep changing it whenever I change the orientation of the camera 90 degrees from landscape to portrait and back to keep the proper alignment, especially with the lens hood on. Any ideas about how to simplify the process to easily ensure the correct polarizer alignment each time?
Thanks!

How much simpler can it get? Rotate a circular lens filter? Here's an idea, get someone else to do the rotating portion for you.

Okay I can’t take it anymore. If you use a polarizing filter you HAVE to manually turn the ring; it is easy and simple to so. It works most efficiently when 90 degrees from the sun.
While looking through the viewfinder to see where the maximum desired effect is happening I either watch to see the sky darkening of lightning; or if the reflection I am trying to minimize is minimizing or not. It is fun to watch the image change while you are moving it around to get it where you want it; sometimes not necessarily at its maximum effect.
While I shoot large format cameras the system works the same. I find them to be the most valuable filters in my bag. It enhances textures on things you would not even think were being affected by reflection.

I agree with the rubber lens hood solution. They also collapse for the wide angle shots.

Polarization is all about angles set by the sun angle. There is no substitute orientation for you.

At one time I believe Tiffen made a polarizer that had a post on the outside of the ring. When you got ready to go vertical from horizontal (or vice versa), you would locate that post's position, change the camera position, and relocate that post back to its former position.
I used one of those in the 1960s. The purpose of the post was to provide a mounting point for a small, accessory polarizer (neither polarizer was circular). The accessory filter allowed viewing of the effect of the filter while it was mounted on a range finder camera (or the post could be used to identify desired orientation before mounting the filter). The accessory filter was removable so that it would not get in the way when using a SLR.

I also look through the viewfinder or for some, Liveview. I suspect everyone does it that way.

Stop moving.
When you change the direction the light is coming from, you have to reorient the polarizer. Is this rocket science?

Or ANY hood that screws onto the filter.

The OP understands that concept. What the OP wants is an easy way to go from horizontal to vertical, and vice versa, for the same shot and easily relocate the filter the exact required 90°. Most suggestions so far are just to visually relocate the filter using the viewfinder. I do not believe that is what the OP is looking for. I think the OP is looking for a solution without initially looking through the viewfinder. A few of us have given the OP the best suggestions that we know of to be able to do that.

If you mean that you have to remove the lens hood to turn the polarizer filter after you change positions and then install the lens hood, again, I can only suggest that you buy a rubber lens hood and screw it into the polarizing filter. Since you are using a 17-40mm lens, make sure the lens hood is for a wide angle lens and you won't have to take of the lens hood.
